The Climatic Research Unit e-mail hacking incident refers to a November 2009 incident involving the hacking and leaking of e-mails and documents on climate change research from the Climatic Research Unit of the University of East Anglia U.K.

Excerpts from the leaked correspondence have been promoted by global warming sceptics, who say the private correspondence shows that climate scientists conspired to overstate the case for a human influence on climate change.
